The exploitation of two-dimensional (2D) vanadium carbide (V2CTx, denoted as V2C) in electrocatalytic hydrogen evolution reaction (HER) and nitrogen reduction (NRR) is still the stage theoretical study with limited experimental exploration. Here, we present studies V2C MXene-based materials containing two different bismuth compounds to confirm possibility using a potential electrocatalyst for HER NRR. In this context, first time, employed methods synthesize 2D/0D 2D/2D nanostructures. V2C/BVO consisted BiVO4 (denoted BVO) nanosheets wrapped layers which were synthesized by facile hydrothermal method, whereas V2C/Bi spherical particles Bi (Bi NPs) anchored on MXenes solid-state annealing method. resultant catalyst was proven be beneficial 0.5 M H2SO4 compared pristine V2C. We demonstrated that structure can favor higher specific surface area, exposure more accessible catalytic active sites, promote electron transfer responsible optimizing activity. Moreover, has superior stability an acidic environment. Whilst observed could highly efficient NRR purposes. Our results show ammonia (NH3) production faradaic efficiency (FE) reach 88.6 μg h-1 cm-2 8% at -0.5 V vs. RHE, respectively. Also exhibited excellent long-term stability. These achievements high performance terms highest generated NH3 recent investigations MXenes-based electrocatalysts. Such activity attributed effective suppression main competitive

Ammonia is one of the most widely produced chemicals worldwide, which consumed in fertilizer industry and also considered an interesting alternative energy storage. However, common ammonia production energy-demanding leads to high CO2 emissions. Thus, development methods based on available raw materials (air, for example) renewable sources highly demanding. In this work, we demonstrated utilization TiB2 nanostructures sandwiched between coupled plasmonic (gold nanoparticles gold grating) photoelectrochemical (PEC) nitrogen reduction selective production. The plasmon structure allows us reach efficient sunlight capture with a subdiffraction concentration light space, where catalytically active flakes were placed. As result, PEC experiments performed at -0.2 V (vs. RHE) simulated illumination give 535.2 491.3 μg h-1 mgcat-1 yields, respectively, pure air as source. addition, number control confirm key role coupling increasing yield, selectivity production, durability proposed system. Finally, have series numerical quantum mechanical calculations evaluate contribution activation surface, indicating increase catalytic activity under plasmon-generated electric field.
